Photovoltaic bracket welding installation method

What type of mounting structure is used for PV panels?

This mounting structure is often used for residential systems. Helical piles. In sites with weak granular soils, helical piles are driven deep into the ground and attached to the PV panels. They can withstand uplift forces caused by the soil expanding or by strong winds as the helixes in the poles keep them fixed in place.

What is the Sun approach angle for a ballasted roof mount?

The sun approach angle of the Ballasted Roof Mount system varies depending upon the amount of ballast required for your installation and whether or not Wind Deflectors are utilized. The sun approach angle for most installations will be 17 degrees. The row spacing for this system is 21.97 inches (module to module).

What is a seismic anchor & microinverter bracket?

Seismic Anchor: Secures the Ballast Tray directly to the building structure through roofing material and/or decking. Provides seismic lateral stability for module array. Microinverter Bracket: Attaches to Ballast Tray and secures microinverter. Works with Enphase, SolarEdge and DirectGrid microinverters.

How do you attach a PV module to a rail?

Module Clamp: Secures the PV module to the rail. Use four clamps for each Ballast Tray, two on north and south two Ballast Trays. Multiple sizes available depending on thickness of PV module. Wind Deflector: Joins Ballast Trays together into a continuous structural member. Distributes and reduces loading on roof structure.
